Description
Technical field
The present invention relates to a kind of horizontal continuous casting graphite crystallizer.
Background technology
At present, the technology of becoming a useful person of copper pipe strand is two kinds basically both at home and abroad, the one, and the continuous casting and rolling method, another is an extrusion.Extrusion is low owing to the extrusion technique level, and the degree of eccentricity of product is big, and is in light weight, and lumber recovery is low, the cost height, and the energy consumption height will progressively be withdrawn from the market in keen competition.The continuous casting and rolling method is compared with traditional extrusion, it is low to have cost, energy consumption is little, the efficient height, characteristics such as lumber recovery height, thereby obtained developing faster, but also exist following problem in process of production: because the problem on the present graphite crystallizer structural design of using, strand with continuously casting and continuously rolling technology production, its inner surface exists the crystallization line, the existence of this defective, inner surface at the tubing goods produces the processing trace easily, the processing trace is obvious especially after the pickling, but also the copper powder that appearance is peeled off in a large number in the plastic forming process easily, will produce problems during the VAS application-to-terminal service product, as evaporimeter at air-conditioner, be easy to generate " dirty stifled " phenomenon in the use of condenser, can cause the seepage of air conditioner two-unit product to scrap when serious; And because easy phenomenon of peeling off in a large number at the inner surface generation processing trace or the copper powder of tubing goods has also limited use and the further deep processing moulding of this series products in pipe valve class auxiliary facility.The crystallization line defect that occurs when solving moulding, the technical staff also attempts structure that the crystallizer inner core is designed to identical cone angle and shrinks along Way out, and adopt and instead to push away the generation that technology reduces the crystallization line, but the crystallization line that still can not well solve the strand inner surface is eliminated problem.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of horizontal continuous casting graphite crystallizer, use its inner surface of copper pipe strand of this horizontal continuous casting graphite crystallizer continuous casting smooth, can there be the crystallization line, improved the Forming Quality of strand, eliminate potential hidden danger of quality, more helped further deep processing moulding.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: horizontal continuous casting graphite crystallizer, comprise that overcoat cylindrical shell and tail end are connected the inner core of overcoat cylinder back-end, be provided with the circular passage between inner core and overcoat cylindrical shell, have the inlet that communicates with described circular passage on the diapire of inner core rear end, it is characterized in that: the axial region of described inner core comprises first service portion and second service portion that connects successively from tail end head-end direction, the cone angle of described first service portion is greater than the cone angle beta of second service portion, cone angle and cone angle beta ratio 〉=2.5.
The junction of described first service portion and second service portion is a smooth transition.
A kind of preferred, described cone angle and cone angle beta ratio are 3.0.
Preferably, described cone angle is 1.0 °～1.5 °.
Improved, the front end of second service portion also is provided with the 3rd service portion on the described axial region, and the cone angle gamma of described the 3rd service portion is greater than the cone angle beta of second service portion, but is not more than the cone angle of first service portion, and cone angle gamma and cone angle beta ratio are 〉=2.0.
Equally, the junction of described second service portion and the 3rd service portion is a smooth transition.
A kind of preferred, described cone angle gamma and cone angle beta ratio are 2.5.
Preferably, described inlet is six of even annular spread.
The present invention is owing to adopt technique scheme, adopt the billet withdrawing technology of " drawing-counter pushing away-stop-La ", copper liquid is in the dynamic process of crystallization, reduce the copper crystalline temperature fluctuation of liquation state admittedly by the anti-technology that pushes away, make its uniform crystal particles, counter pushing away in the process, because the different cone angle structure between inner core axial region first service portion and second service portion, and the smooth transition structure of first service portion and the second service portion junction, copper liquid solidifies trace and the inner core conical surface pushes the generation that can more effectively avoid the crystallization line when rubbing stone roller, thereby obtain light face strand.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of horizontal continuous casting graphite crystallizer;
Fig. 2 is an A-A place view among Fig. 1;
Fig. 3 is the structural representation when using for horizontal continuous casting graphite crystallizer of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, structural representation for horizontal continuous casting graphite crystallizer of the present invention, comprise that overcoat cylindrical shell 1 and tail end are connected the inner core 2 of overcoat cylindrical shell 1 rear end, be connected by pin 9 between inner core 2 and overcoat cylindrical shell, 1 of inner core 2 and overcoat cylindrical shell are provided with circular passage 3, have the inlet 21 that communicates with described circular passage 3 on the inner core 2 rear end diapires 20, described inlet 21 can be designed as six of even annular spread, the axial region of described inner core 2 comprises that from tail end head-end direction first service portion 22 and second service portion, 23, the second service portions 23 that connect successively do not have the Main Stage that the crystallization line produces for the crystalline forming inwall of strand; The cone angle of described first service portion 22 is greater than the cone angle beta of second service portion 23, its cone angle ratio 〉=2.5, and cone angle is 1.0 °～1.5 °; First service portion 22 and the 23 junction smooth transition processing of second service portion.The front end of second service portion 23 also is provided with the 3rd service portion 24 on the described axial region, the cone angle gamma of described the 3rd service portion 24 is greater than the cone angle beta of second service portion, but be not more than the cone angle of first service portion, cone angle gamma and cone angle beta ratio 〉=2, described second service portion 23 and the 24 junction smooth transition processing of the 3rd service portion help the strand demoulding.Above-mentioned first service portion, second service portion and the 3rd service portion are partly illustrated for double dot dash line in Fig. 1.
For the size of cone angle, cone angle beta, cone angle gamma, and cone angle and cone angle beta ratio, cone angle gamma and cone angle beta ratio, can adopt following embodiment:
As Fig. 3, the structural representation when using for horizontal continuous casting graphite crystallizer of the present invention, 4 is the copper overcoat among the figure, and 5 is first cooling system, and 6 is second cooling system, and 7 is that copper liquid, 8 is the smelting furnace brick cup.In the strand forming process, adopt the billet withdrawing technology of " drawing-counter pushing away-stop-La ", copper liquid is in the dynamic process of crystallization, reduce the copper crystalline temperature fluctuation of liquation state admittedly by the anti-technology that pushes away, make its uniform crystal particles, counter pushing away in the process, because the different cone angle structure between inner core axial region first service portion and second service portion, and the smooth transition structure of first service portion and the second service portion junction, make copper liquid solidify trace and the inner core conical surface and rub in extruding and can more effectively avoid the generation of crystallization line when grinding, thereby obtain the strand of inwall light face.
